Conveyor arrangement for loose material, especially blasting materials for sand-blasting installations

Abstract

A conveyor installation for loose material, especially blasting materials for sand-blasting installations, includes on the hall floor, respectively, blast chamber floor at least one longitudinal conveyor (1, 2, 3, 4) and at right angle thereto at its conveyor end in the same plane a cross-conveyor (5). These conveyors (1, 2, 3, 4, 5) operate by the use of conveyor members (27, 28) which are suspended in a pneumatically driven reciprocating frame (19, 24, 33). The frames (19, 24, 33) include lateral girders (20, 21; 31, 32) which are connected by webs (22). The frames run on rollers (11 to 18, 34, 36) which project from boundary profiles (6, 7, 8, 9, 10). The latter delimit laterally the longitudinal conveyors (1, 2, 3, 4). The cross-conveyor (5) includes a boundary profile (35) with rollers (34) only at the side opposite the longitudinal conveyors whereas on the side facing the longitudinal conveyors the rollers (36) are provided at the end faces of the boundary profiles (7, 8, 9 ) of the longitudinal conveyors. For creating a free passage from the longitudinal conveyors to the cross conveyor, the frame girder (31) thereof which faces the longitudinal conveyors, is constructed with a short vertical leg.

I claim:

       2. A conveyor installation according to claim 1, comprising additional roller means supporting said further frame means, some of said additional roller means being arranged on end faces of said profile means on the side thereof facing the cross conveyor means. 
     
     
       3. A conveyor installation according to claim 2, wherein others of said additional roller means are supported on further boundary profile means outside the termination area of said first conveyor means. 
     
     
       4. A conveyor installation according to claim 3, wherein the frame means and further frame means of the longitudinal conveyor means and of the cross-conveyor means include lateral girder-like members having mutually oppositely disposed, approximately vertically directed retaining projections. 
     
     
       5. A conveyor installation according to claim 4, wherein the conveyor members are suspended in said retaining projections. 
     
     
       6. A conveyor installation according to claim 5, wherein said projections are constructed as nose-like sheet metal members and the conveyor members are constructed as V-shaped angularly bent sheet metal members with a long and a short leg in cross section. 
     
     
       7. A conveyor installation according to claim 6, characterized in that the girder-like members have a T-profile whose one horizontal profile web rests on the roller means, whereas the other horizontal profile web overlaps the conveyor members along the edge. 
     
     
       8. A conveyor installation according to claim 7, further comprising a cup-type conveying device for conveying the loose material in the upward direction, said conveying device being located in the conveying plane of the longitudinal conveyor means and of the cross conveyor means adjoining the conveyor end of the latter. 
     
     
       9. A conveyor installation according to claim 1, wherein the frame means and further frame means of the longitudinal conveyor means and of the cross-conveyor means include lateral girder-like members having mutually oppositely disposed, approximately vertically directed retaining projections. 
     
     
       10. A conveyor installation according to claim 9, wherein the conveyor members are suspended in said retaining projections. 
     
     
       11. A conveyor installation according to claim 10, wherein said projections are constructed as nose-like sheet metal members and the conveyor members are constructed as V-shaped angularly bent sheet metal members with a long and a short leg in cross section. 
     
     
       12. A conveyor installation according to claim 9, characterized int hat the girder-like members have a T-profile whose one horizontal profile web rests on the roller means, whereas the other horizontal profile web overlaps the conveyor members along the edge. 
     
     
       13. A conveyor installation according to claim 1, further comprising a cup-type conveying device for conveying the loose material in the upward direction, said conveying device being located in the conveying plane of the longitudinal conveyor means and of the cross conveyor means adjoining the conveyor end of the latter. 
     
     
       14. A conveyor installation for loose material, especially blasting materials for sand-blasting installations with at least one longitudinal conveyor means which terminates in a separate cross-conveyor means, the conveyor means having a large number of conveyor members reciprocable in the conveying direction and operable to fold over, the longitudinal conveyor means and the cross-conveyor means being arranged in one and the same plane, the longitudinal conveyor means including stationary lateral boundary profile means disposed substantially parallel to one another and provided with roller means projecting toward one another, frame means constructed as carriage and supported on said roller means, the conveyor members being suspended on said frame means, the analogously constructed cross conveyor means being laterally open within the area of termination of respective longitudinal conveyor mean, and further frame means for carrying the conveyor members of the cross conveyor means, said further frame means being also supported on further roller means. 
     
     
       15. A conveyor installation for loose material, especially blasting materials for sand-blasting installations with at least one longitudinal conveyor means, the longitudinal conveyor means having a large number of conveyor members reciprocable in the conveying direction and operable to fold over, the longitudinal conveyor means including stationary lateral boundary profile means disposed substantially parallel to one another and provided with roller means, frame means supported on said roller means, the conveyor members being supported on said frame means, characterized in that the longitudinal conveyor means terminates in a separate cross-conveyor means, both said longitudinal and cross-conveyor means being arranged in one and the same plane and the cross conveyor means being laterally open within the area of termination of respective longitudinal conveyor means, in that the cross-conveyor means is provided with additional roller means, at least some of said additional roller means being arranged on end faces of said profile means on the side thereof facing the cross-conveyor means, and in that further frame means are supported on said additional roller means and carry conveyor members of the cross-conveyor means.
